ПРИМЕНЕНИЕ АУТОЛОГИЧНОЙ МИКРОФРАГМЕНТИРОВАННОЙ АДИПОЗНОЙ ТКАНИ В ЛЕЧЕНИИ ПОСТЛУЧЕВОГО ЯЗВЕННОГО ПРОКТИТА

Abstract

Introduction. Post-radiation ulcerative proctitis is a serious complication after radiotherapy for cancer of the prostate, cervix and uterine body, anal canal, and other pelvic tumors. Given the mechanism of occurrence, there are currently no pathogenetic methods for the treatment of post-radiation ulcerative proctitis. Aim. Is to develop a technique and evaluate its effectiveness in the treatment of patients with post-radiation rectal ulcers using autologous microfragmented adipose tissue. Material and methods. The study included 30 patients, of which 24 (80.0% were women and 6 (20.0%) were men. Manual lipoaspiration was used to obtain autologous adipose tissue. Then, microfragmentation was performed through transfers. The introduction of autologous concentrated adipose tissue was performed in edges of post-radiation ulcerative defect of the rectal wall under endoscopic control. Results and discussion. The duration of the manipulation from the moment of adipose tissue sampling to the end of the injection was a little more than an hour (Me = 75.0 min). No intraoperative complications were identified. One patient (3.3%) had a local recurrence of cervical cancer, and therefore the patient was excluded from the study. Control rectoscopy after 6 months in 28 (93.3%) patients showed complete epithelialization of post-radiation ulcerative defects of the rectum. Conclusion. The technique of using autologous microfragmented adipose tissue is affordable and effective in the treatment of patients with post-radiation ulcerative proctitis
